Purpose:
The aim of this study was to characterize implants coated with hydroxyapatite (HA) using 2 different processes.
Materials And Methods:
Commercially pure titanium implants were coated with HA using a modified biomimetic process and the plasma spray process. These implants were characterized by scanning electron microscopy, Fourier-transformed infrared spectroscopy, and x-ray photoelectron spectroscopy.
Results:
The plasma spray process generates a typical rough topography mainly consisting of HA. The HA coating produced by biomimetic process was partially dissolved in water and only a very thin layer of calcium titanate plus calcium phosphate and probably beta-tricalcium phosphate remained. In vitro test showed that both coatings can be considered bioactive.
Conclusion:
The modified biomimetic process seems to be a simple and low-cost alternative to coat titanium with a high potential of In vitro application.
